Boku no Kanojo ga Majimesugiru Sho-bitch na Ken

Since his first year of high school, Haruka Shinozaki has been drawn to the class representative, Akiho Kousaka. She is a model student in every way, gorgeous, and athletic. Shinozaki chooses to reveal his affections since they are in the same class this year, and to his surprise, Kousaka accepts to be his girlfriend! But Kousaka turns out to be a little odder than he initially imagined—this seemingly ideal girl has never been in a committed relationship. Despite her lack of experience, she makes a commitment to do everything in her power to win Shinozaki's favor, including mastering all of his obsessions or various sex positions. Shinozaki tries to reassure her that she doesn't need to study these topics, but Kousaka dedicates herself to making him happy in numerous ways.
